Yeah, I read the link you posted and no one in the article does the author even hint that Tubby was a "MUCH" better recruiter. He clearly expresses that they were very equal.
Main difference being Tubby started off with a bang, a 9 person class that sure, it got rated #10, but they always rate classes better the more players are in it, and 5 person classes are considered HUGE, so a 9 person class is just ridiculous and honestly ends up producing problems down the road unless you lose several of those 9 players to the NBA or to a transfer and reshirt at least a few of them as well.
And of those 9 players, the highest rated one was a horrible recruit. He didn't have the grades/test scores to even get in, did he? And he had character issues as well, didn't he? I can't remember honestly, but did he even play a full season for the Gophers? Take out Royce White from that bloated class and it wasn't all that impressive.
And then after that one big year, he followed that up with 4 straight years of nothing or classes not even Top 50.
On the other side, Pitino's last 3 classes are all in the Top 50 range, with the #80 ranked player already committed for the 2021 class.
Tubby got WORSE as time went along, and the main reason he got fired.
Pitino's getting BETTER as time goes along, and is seemingly why he is still here.
